"That equates to almost $120,000 (42.414t x 28%)in antimony and over 17000 ounces of gold / $20.4Million, "Just a tiny piece of the Nolan""

I'm afraid you dropped a factor of 1000 from the antimony value...

it's 42,414 tons ore x 28 tons Sb/100 tons ore (ie, 28%) x $10,000/ton Sb = $118,759,200 in Antimony.
